Soketi

Next-gen, Pusher-compatible, open-source WebSockets server. Simple, fast, and resilient.

It's cheaper, fast, and you can deploy it anywhere.

• Cheaper than any competitor: This is because you pay only for your infrastructure. Whether it's your basement server or cloud, it fits and runs. It can be as cheap as $5 on DigitalOcean.
• Blazing fast: Guaranteed core message delivery in less than 100ms. Written on top of C, ported to Node.js. Built with one of the fastest available technologies.
• Pusher compatible: You don't need to replace your existing code. It's using the Pusher Protocol v7. This means you just connect to the server.
• Ready for production: You can scale to hundreds of servers with Redis or NATS and you won't lose performance. It is resilient enough so you can have a good night sleep.
• Built-in app management: Just like Pusher, you can define your own app credentials. You don't even need Pusher for it, and you can read from any database.
• HTTP Webhooks: Trigger HTTP requests whenever a channel gets occupied. Pair it with Lambda functions and soketi will invoke them for you.
